Specification of Letters latent. Patnted Nov 24 1914 Application filed September 30, 181;. fierlhl 10.79135.

To all whom it may concern:

Be it known that Mass Uuo, a subject of the Emperor of Japan, residing at Oakland, in the county of Alameda and State of California, have invented new and useful Imand Cleaning Devices, of which the 0 lowing is a specification.

This invention relates to a cleaning and polishing device.

It is the object of this invention to provide means in a cleaning and polishing device for moistening a continuous polishing member at a predetermined point on its polishing-surface, which means is simple in construction and efficient in operation.

Further objects will appear hereinafter.

The invention primarily resides in a rotary polishing member, means for revolving said member continually, and means for automatically moistening said. polishing member at a certain point on its periphery at each revolution thereof so as to provide alternate wet and dry surfaces thereon.

The invention further consists of the parts and the construction. and combination of parts as hereinafter more fully described and claimed, having reference to the accompanying drawings, in Which, I

Flgure 1 1s a front elevation of the invention, with parts broken away. Fig. 2 is a side elevation of same. Fig. 3 is a detail plan View, with parts removed. Fig. 4 is a detail section and elevation on the line a-a of'Fig. 3. Fig. 5 is a view in elevation of amodified form of the invention, with parts removed. Fig. 6 is an end view of same In the drawings A represents a frame of any suitable construction, providedbvith a hand-hold 2. Mounted on the frame A in suitable'bearings is a drive shaft 3 which may be rotated from any suitable source of power, but is preferably driven by means of an electric motor 4, carried by the frame A. iigidly mounted on outwardly projecting arms B on the frame A. is a shaft 5 which extends parallel to the shaft 3 and is spaced a suitable distance therefrom. Revolubly mounted on the shaft is a drum 6, having a grooved wheel 7 rigidly secured thereto. A. beltS is rove around the wheel 7 and passes around a corresponding wheel 9 on motionmay be transmitted to the drum 6 from the drive shaft 3. Rig-idly mounted on the stationary shaft 5, adjacent each end thereof, are outwardly extending arms 10.0 the outer ends of which a roller 11 is revolubly mounted. A polishing belt 12 is ro've around the drum 6 and roller 11, and is formed ofany su table material. Means are providedtor anoisteniug the belt 12 at a certain point on each revolution thereof. This means is here shown as consisting of 9. moistoning roller 14, carried on a slidable frame 15, supported on the arms 10, which frarfie is normally positioned by means of springs 16 hearing between" adjustable collars 17 on the'arms' 10, and slidable sleeves 18 to which the frame 15 is attached; the springslfi acting to normally retain the moisteningroller 14 out ofcontact with the belt 12. A hopper 1:9, containmg the moistening polish, is carmed on the frame 15, and extending the length of the roller 14 has a discharge opening on its underside with which the roller 14. is in constant contact.- The surface of the roller 14 may be formed of'any suitable absorptive material.

Loosely mounted on' the stationary shaft 5 1s aadisk 20 and secured'to a sleeve ,205 formed integrally with disk 20 is a cam'disk'21. and attached'to the ing band 22 on engaging the pin 24 on thedisk 20, rotates the latter half a revolution, and in so doing causes the cam face 21 thereon to engage a roller 25 on the frame 15 and thereby reciprocate the latter in opposition to the springs 16 and move the moistening roller 14 into contact with the belt 12; the moistening roller 14 remaining in contact with the belt 12 a length of'time regulated by the length of the acting face of the cam 21. When the cam 21 passes beyond the roller 25. the springs 16 operate to move the moistening roller 14 out of contact with the belt 12. Continued rotation of the belt 12 causes thefinger 23 to engage the pin 24, and thereby cause the .disk 20 to rotate another half revolution, and there by dispose the pin 24 in position to be reengaged by the finger 23. In thismanner the belt 12 is caused to have alternate moistoned and dry portions.

In the operation of the device the surface to be polished is acted on by the portion of the belt passing around the roller 11. Means are provided for removing dust from the surface to be polished priorto the application of the belt 12. This means consists of .a rotar brush 26, mounted on a revoluble shaft 2 carried on the outer ends of ad justable arms 28, turnable on the stationary shaft 5. The brush 26 is designed to be continuously rotated from the drive shaft 3,

for which purpose groove pulleys 29 are.

mounted on' the ends of the shaft-27 around which belts 30 are rove. The belts'30 pass around double groove ulleys 31, loose on the fixed-shaft 5, whic are adapted to. be rotated vfrom the shaft'3 by means of belts 32 which pass around the pulleys .31 and corresponding pulleys 33 on the shaft 3. The "arms 28 are suliiciently tight on the fixed shaft 5 to frictiorially engage the latter to retain the 'arms in any desiredangu- .lar position, the double gtmlleys- 31 permitting rotation of the she.

27 and brush. 26 irrespectiye of the position of the arms 28.

,In the modified form of the invention shown in, Figs; 5 and .6, the drum '6 is Cuvered with a suitable polishing material 12,

which serves in lieu of the belt 12 The roller 11 is thus dispensed with in' this form of the invention. The polishing surface 12" is moistened at intervals by means of the moistening roller. 14 1n the manner-before descri bed.

Having thus described my invention what I, claim and-desire to secure by-Letters Pat ent, is:

1. A cleaning and olishing,device ing.

0 e, rotary polishing and brush members, means for relatively adjusting and revolving said] members,

cluding a portable: y

means to intermittently moisten the polishing member consisting of arms slidable radially through the axis of the polishing member, a drum and moistening' means carried by said, arms, cams by which the arms and roller are intermittently advanced, and returning springs surrounding the arms.

2. In a cleaning andpolishing device,the

combination with'a drive shaft,- arevoluble polishin member, and means controlled'by the polis ing member for actuating the cam at intervals.

4. In a polishing and cleaning device, the combination 'of'a revoluble drum, a polishing member carried bysaid drum, means for rotating the drum and polishing member continuously, a slidable frame, a moistening roller on said frame, yieldable means acting on said frame to normally maintain the moistening roller out of contact with the polishing member, 'andmeans controlled by the rotation of the polishingmember for-in termittently movingthe moistening roller into and out of contact with the polish ng member. r

therein, a fixed shaft,"a drum on said shaft, connections by which mot1on 1s communicated from the motor to said drum arms -m'ovable about the fixed. shaft,- a rotary cleaning member journaled in the outer. ends of the arms,and means to transmit power from the motor to the cleaning member.

In testimony whereof I have hereunto set my hand in the presence of twosubscribing witnesses.
